The Paleoproterozoic was a critical time in whether modern-style plate tectonics had become globally dominant(e.g., Wan et al., 2020). The Capricorn Orogen witnessed the assembly of the Pilbara and Yilgarn Cratons and an exotic microcontinent, the Glenburgh Terrane, to form the West Australia Craton(WAC) through two collisional orogenic events, the 2215–2145 Ma Ophthalmian and 2005–1950 Ma Glenburgh Orogenies(Johnson et al., 2013; Fig. 1). Compared to other Proterozoic orogenic belts in Australia, the Capricorn Orogen preserves ‘complete' opposing continental margin successions, together with intervening arc fragments associated with oceanic closure and foreland basins associated with collisional loading(Cawood et al., 2009).

The evolution of the Tethys Ocean involved several episodes of ocean opening(including the Paleo-Tethys and Neo-Tethys) along its southern margin as terranes rifting away from eastern Gondwana. These oceans were terminated by well observed north-dipping subduction as the same terranes accreted to southern Eurasia. However, the presence of south-dipping subduction, though geologically proposed by numerous studies, have generally been omitted in the reconstruction of Tethyan evolution. Here, we synthesize the Mesozoic south-dipping subduction evolutions in the global reconstruction and focus on two potential events located along the northern edges of Southwest Borneo Block and the Woyla Arc. We next evaluate their slab volumes after thermal diffusion in the current mantle. Fast velocity anomalies in the mantle beneath the same region are then converted to cold anomalies and their volumes are further estimated and compared to the volumes evaluated from these two Mesozoic south-dipping subduction. We further identify seismic fast velocity anomalies likely relevant to slab remnants of south-dipping Tethyan subduction in the present-day mantle beneath the Indian ocean and West Australia, and link them to arc systems in plate reconstructions. In addition, one more tectonic scenario relevant to the north-dipping subduction in our study region is also examined. We speculate the relationship and evolution between such south-dipping subduction and north-dipping subduction in the south of Tethys Oceans. The attempt to reconstruct intermittent south-dipping subduction systems in southern Tethys region represents an effort on assessing rifting mechanisms in the opening of the Tethys Ocean and break-up of eastern Gondwana.

Guangdong Province in the central Cathaysian Block has two world-class metallogenic belts, namely, the Nanling and Southeastern Coastal Metallogenic Belts(NLMB and SCMB), which are spatially coincide with the major regional Ganjiang and Zhenghe-Dapu Fault Zones(GJFZ and ZDFZ). However, what roles the faults played in mineral deposition and magmatism is unclear. Using ambient noise tomography, we obtain a 3-D whole-crust shear wave velocity model. By combining available regional geophysical models, we characterize the architecture of the regional shallow lithosphere and infer its possible tectonic connection to magmatic sources, pathways and surface deposition. The results show that the study area is loosely divided by the two major faults, the GJFZ and ZDFZ, into distinct velocity domains. In the north high Vand low V/Vcrust in the NLMB imply crustal remelting, which leads to the general felsic composition. In the coastal area, the lower crustal high Vanomaly is attributed to upwelling melts associated with Cretaceous magmatic activity. Between mineral belts, a swath of crustal lowvelocity zones extend into the uppermost mantle, manifesting partial melting related to upwelling magmas that may hint at a deep origin of magma from subcrustal lithosphere and likely feed surface mineral deposits through major faults. Secondary NW-trending faults coincide with low velocities and facilitated magmatic migration. A correlation between coastward extension of low velocities and younging of the Jurassic and Cretaceous magmatism is suggestive of a combined effect of slab rollback and a change in the direction of the Paleo-Pacific subduction system. We speculate a regional fault-control model in the central Cathaysian Block for the spatial-temporal evolution of regional deformation and magmatism during the middle Mesozoic.
